After 5 years with 5 Billigheimer bags (all eventually broken, especially to the eyes) more money is spent than for good. So I bought the Gelert Cargo Bag with 120 liters volume - and am absolutely thrilled for over a year, the bag is (bridging a long-distance relationship, with the ICE) every 14 days in use; Further, even with so many motorcycle tour: stable, practical, endlessly loadable, no manufacturing defects, no wear and tear. For some events / rides me the great model, however, was too bulky, so ordered as an alternative, this version with 90 liters: and just as satisfied. It's worth it (at least sometimes) Yes, once spending a little more money (instead of five seemingly "little"). At least for these cargo bags.
